Why do you really like that? 3840x2160 is exactly double 1920x1080, which is a useful property.

- pazra 11y agoThey've used the DCI 4K resolution standard as the basis for their 4k screen, which is defined as 4096 x 2160 at 16:9 aspect ratio. This screen has a 16:10 aspect ratio, thus 4096/16*9 = 2304, the vertical resolution on the 4K iMac.
- thrownaway2424 11y agoI'm afraid I didn't quite follow you there. Is one of those things using non-square pixels?
- dubya 11y ago4096:2304 is still 16:9.
- Tepix 11y agoI read it a couple of times, I think that's what he is saying why they chose that resolution.
- Tepix 11y agoI agree that it's useful for a TV but the 21.5" iMac is too small for that anyway - however if you want to edit 4k video, it's super useful to have extra pixels to be able to display a full UHD image with some GUI elements surrounding it.
